Backs bear a heavy burden
Date:2/21/2013

cal loads, defined as the amount of force or deformation placed on a particular area of the body, were transferred beneath the skin to cause damage to tissue and internal organs.

Based on data collected by MRI, Profs. Gefen and Epstein developed anatomical computer models of the shoulders. These showed how pressure generated by the weight of a backpack load is distributed beneath the skin and transferred to the brachial plexus nerves. The models also account for mechanical properties, such as the stiffness of shoulder tissues and the location of blood vessels and nerves in the sensitive areas which are prone to damage.

Extensive mechanical loading was seen to have a high physiological impact. "The backpack load applies tension to these nerves," explains Prof. Gefen. He notes that the resulting damage "leads to a reduction in the conduction velocity that is, the speed by which electrical signals are transferred through the nerves." With a delay or reduction in the amplitude or the intensity of signals, nerve communication cannot properly function, he says.

A danger to adults and children

These results apply to people from all walks of life, says Prof. Gefen. Many professions and leisure activities, such as hiking or travelling, involve carrying heavy equipment on the back. The researchers plan to extend this study in two directions: first, to study the effects of load on nerve conductivity, and second, to examine the impact of these heavy loads on a child's anatomy.

School bags are a major concern, he warns. It cannot be assumed that children's bodies react to shoulder stress in exactly the same way as adults. Differences in physiology could lead to different consequences, tolerance, and damage levels.
